WARNINGS
•
Air shutter adjustment should
only be performed by a quali-
fied professional service tech-
nician.
•

in place and sealed during
adjustment.
CAUTIONS
•
Soot will be produced if the
air shutter is closed too much.
Any damage due to sooting,
resulting from improperly
setting the air shutter, is not
covered under the warranty.
•
The air shutter door and
nearby appliance surfaces
are hot. Exercise caution to
avoid injury while adjusting
flame appearance.
1. Refer to Figures 9, 10 and 11 for proper
flame appearance. To adjust the flame,
rotate the adjustment rod toward the back
or toward the front of the fireplace (rod
located in the lower control area). Position
the air shutter to the factory setting as
shown in the table in Figure 12.
2. Light appliance (follow lighting procedure
on lighting label in control compartment
or see the Care and Operation Manual).
3. Allow the burner to operate for at least 15
minutes while observing the flame con-
tinuously to ensure that the proper flame
appearance has been achieved. If the
following conditions are present, adjust
accordingly.
• If flame appears weak or sooty, adjust
the air shutter, incrementally, to a
more open position until the proper
flame appearance is achieved.
• If flame remains blue, adjust the air
shutter, incrementally, to a more
closed position until the proper flame
appearance is achieved.
4. Leave the control knob (off/pilot/on)
in the ON position and the burner OFF/
ON switch OFF (and remote switches, if
applicable).
5. When satisfied that the burner flame ap-
pearance is normal, re-install the lower
control compartment door then proceed
to finish the installation.

The pilot flame should be steady, not lifting
or floating. Flame should be blue in color with
traces of orange at the outer edge.
The top 3/8" (10 mm) at the pilot generator
(thermopile) and the top 1/8" minimum (tip)
of the quick drop out thermocouple should be
engulfed in the pilot flame.
The flame should project 1" (25 mm) beyond the
hood at all three ports (see Figure 13). Replace
logs if removed for pilot inspection.
To light the burner; turn “ON” the remote wall
switch and rotate the gas valve control knob
counterclockwise to the “ON” position (“ON”
will be at the top side of the valve).
Electronic Appliance Checkout
To light the burner, turn ‘ON’ the unit mounted
On/Off switch or the optional remote wall switch.
Ensure the igniter lights the pilot. The pilot
flame should engulf the flame rod as shown
in Figure 14.
